I have accesses to a Bench grinder at my Dad's office, and I would like to know if a Bench grinder will work just as well for sharpening blades as a blade grinder. I have seen some of the prices for blade grinders and they are through the roof (new). I don't really want to buy a used one either. I could use my old boss's blade grinder but I don't want to be rude and ask him. So will a bench grinder suffice for sharpening blades? Even if I have to angle the blade a bit? thanks for any input.
